Html page scroll issue

[nitinkabra]

I am working on a project in which i have to display certain data row. I am using table for that purpose.

Here's a demo

Now the problem is whenever i change the selection of row or scroll the current row, it goes hiding up or down . How do I fix the scroll so that it shows the current row ?

Please add below code in your js.

var globalvar;
function newfunc(val){
globalvar=val;            
} 
and also add onclick on each tr like below example.
<tr id="42" tab_id="30" tabindex="30" class="data_row" onkeydown="keydwn(event,this.id);" onclick="newfunc(this.id);">
